Rugged and Usable
The STi's rugged magnesium case means solid protection for your investment. The coiled and direct-wire SmartPlugs provide a convenient mute button on your plug, for quickly muting alerts. The ultra-bright 280-LED alphanumeric display is easy to read from any angle, and gives you the information you need, from radar and laser alerts (the display provides actual numeric radar frequency for any radar signal along with visual indication of alerts) to Safety Warning System (SWS) messages about upcoming hazards, construction and more. Easy-to-use programming lets you customize up to 9 features, including programmable bands, SWS on/off, and more.

Best-in-Class Detection
The STi Driver includes full X, K, SuperWide Ka, and Safety Warning System radar capability, front and rear laser detection, Beltronics' patented Mute and AutoMute, audible and visual band alerts, and all the performance you'd expect from Beltronics.

Dual LNA (low noise amplifier) microwave receivers mean you'll get the longest possible warning against all radar threats. Advanced AutoScan processing and digital signal processing (DSP) give you superior range and reduce false alarms to virtually zero. The internal speaker will alert you even in loud vehicles, and high and low voltage warnings are given any time the vehicle's voltage drops below 10.5 volts, or goes above 16.5 volts.

Keep it Hidden
Beltronics' TotalShield RF Technology provides the ultimate in undetectability. The exclusive technology makes the top-of-the-line Beltronics STi Driver detector invisible to radar detector detectors, including the latest technologies like VG-2 and Spectre. You can also dim or turn off the STi's LED display to keep it out of sight.

How TotalShield Technology Works
Beltronics' TotalShield Technology keeps RF signals from radiating from the detector. Unlike other radar and laser detectors, which merely move their RF signals (local oscillators) to another frequency (which will be detectable by future detector-detectors), this revolutionary design keeps you unseen by current radar detector-detectors, including VG-2 and Spectre. This unique design will also keep you unseen from any future radar detector detectors as well.

How Safety Radar Works
Safety Warning System, or SWS, uses a modified K-band radar signal to alert users of Highway Construction or Maintenance, Highway Hazard Zone Advisories, Weather Related Hazards, Travel Information/Convenience, and Fast/Slow Moving Vehicles. The SWS safety radar system has 64 possible messages (60 currently allocated), all of which can be displayed on your STi.

Customer Reviews

I love it, but let me pick at a few small details...
First of all, let me state for the record that regardless of how my statements may appear, I really stick-by my final decision in purchasing this Bel STI unit. In fact, I rated it 5 stars. With everyone else gushing about how great the STI is, I never really saw a review try to pick it apart, no matter how small the detail or the minor annoyance. I wanted to find the things that I wished were different, or could have been done a little better, and express them here to possibly help someone else

Before I purchased the STI, I had other detectors, but my last unit was a Whistler. The Whistler originally had a reputation of being stealthy with the VG2 radar detector-detector (RDD), but I had seen where this wasn't true anymore in regards to other RDD's, so I decided that I wanted something better at being hidden. I had already known about the reputation of Beltronics, and I had looked at Escort as well before I decided to purchase a new detector. Both were good at distances and such, but Escort had a GPS memory for eliminating false signals from such things as motion detectors, and the STI had the ability to remain stealthy to the VG2, VG4, Spectre II III IV IV+, and Stalcar RDD units. The Escort GPS feature was very tempting, but I went with the Bel STI because I felt that being stealthy was a more valuable feature to have over having the ability to map the locations of false radar signals.

After receiving and trying out the STI unit, I found a few things that I missed from my other detector or observed as something that I wished was different. At a very premium price of being over $450, the STI comes with a extremely fancy case, an external speaker, a coiled power cord, a direct connect power cord, and a windshield suction cup bracket. One item that I felt they could have thrown in was an extra bracket for the sun visor.

The power cord connector to the STI is a bit strange. I'm not use to seeing the power end that connects to the STI as a telephone cord connector. It seems like a weak choice, but I can understand that the phone end also supplies a data signal back from the STI unit to the 12 volt power plug to help flash an indicator light related to radar detection. Also, the cord is coiled instead of being a straight wire. I find the coiled wire can be seen from behind better than a straight wire. Of course a person could argue that I should install the more permanet wiring so that it could be hidden, but I was looking at the more typical user and how they might use the temporary power cord more.

The quick release button that helps the unit release from the windshield bracket is located on the top directly where the unit connects to the bracket. I would chosen a side position like some Whistler units have.

The front indicator lights have a brightness control that allows only four choices, one of which is where the lights are off even though the unit is still working. The lowest setting is still too bright at night time, and I would have like to have seen several more reduced brightness levels, and I wouldn't have mind seeing the option of the lights staying on until a radar signal is seen. For trying to be stealthy for the owner, Beltronics hasn't devoted as much attention to hiding the front panel display from other drivers except for when the driver needs the info. Of course, someone could argue the data power cord could be a nod in this direction towards informing the driver when the main unit's display is turned off.

The protective carrying case is nice, but I would have rather they have provided a cheaper case and have spent the money on more features or functions.
Again, there are a few minor annoyances and a few additional changes that I like to have seen done, I would still strongly recommend purchasing the Bel STI for picking up radar at a greater distance and for being stealthy from the current list of RDDs.

best detector.
this is the best detector bar none. completely spectre immune and ships with 2 smartcords for hardwire and 12V lighter socket. remember to check your firmware and make sure it is at least a4m9 or later using the procedure outlined in the radardetector net forums. very happy with my purchase.
only problem is beltronics wont honor their warranty if you buy from amazon! you should get this direct from beltronics if you want a warranty.

Absolutely one of the best RDs which you can buy...
Here is my "short list" of the top performing windshield mount radar detectors which are available from any manufacturer and at any price. This list is grouped in order of decreasing performance. Models within a particular group have nearly identical performance:

Valentine V1
Beltronics STi Driver

Escort 9500ix
Beltronics GX65
Escort 9500i

There you have it. That is the short list of the top performing windshield radar detectors.

In a nutshell, the V1 and the STi are designed primarily for highway driving and long road trips. The models listed in the second group are designed mainly for suburban and city driving since they feature GPS in order to filter out known false alert locations. Those false alerts are caused by either X band or K band microwave automatic door openers and by alarm systems which use radar motion sensors.

The V1 has front and rear antennas plus arrows to indicate where the radar source is located -- front, back, or to the side. Yet the V1 is readily detected by the Spectre radar detector detector (RDD) which is used by police in VA and by the DSP in Texas to nab motorists who are using radar detectors. The STi, on the other hand, is completely immune to detection by the Spectre RDD or any other RDD since the STi does not emit any type of microwave radiation. In short, the STi truly is a stealth radar detector and its steath makes the STi worth its weight in gold.

I have extensively road tested both the V1 and the STi. Both perform very similarly in terms of overall performance, with the V1 having a very slight edge. Yet the STi's stealth, combined with its superior quietness when used in cities or other suburban areas makes the STi the clear winner in my book. The STi, unlike the V1, is also extraordinarily easy to program in order to configure its settings to perfectly suit your needs. My one major caveat regarding the STi is that its built-in speaker isn't very loud. But this issue is easily solved by installing the extremely loud amplified remote speaker which Beltronics includes with the STi. You can hear the remote speaker with the top down and with the radio blaring.

In short, the Beltronics STi Driver is my favorite windshield mount radar detector. It is so good that I use it all the time even though I also have the Escort 9500ci remote installed radar detector and laser shifter system installed in my car. I always operate one or the other radar detector in bar graph signal strength display mode with the other radar detector in radar frequency display mode. This way I not only know how strong a radar threat is, but also the specific nature of the radar threat. For example, 24.7 frequency Ka radar guns are relatively easy to detect, but 35.5 frequency Ka radar guns are harder to detect since these radar guns have very long and narrowly tapered radar antennas. You have to slow down immediately when detecting 35.5 Ka radar since most of the time there is no easy way to determine just how far away the 35.5 radar gun really is.

Finally, although the Beltronics STi Driver is my favorite windshield mount radar detector for my particular driving needs, it may not be the most ideally suited radar detector for you. For example, if most of your driving (or my driving) is suburban/city driving, then I would pick one of the radar detectors which I listed in the second group. On the other hand, if you are a road warrior who logs hundreds of interstate miles every month and if you frequently travel through VA or TX, then the STi Driver is your only real choice. Excluding these two states, then the V1 also is an excellent choice, and at that point it boils down to your own personal preferences as to what features between these two radar detectors which are most important to you.

If you buy a used STi, keep in mind that most likely it will not have any warranty. If you buy an STi from an unauthorized dealer, then it will have no warranty whatsoever. If you buy a used STi, then you should be willing to send it to Beltronics and have it flashed with their latest firmware which addresses several issues and which improves overall performance. Yes, there will be a fee for this service, but on the other hand, a used STi with the latest firmware flash will perform exactly like a brand new STi. Something to think about.

So, there you have it! I always try to cut to the chase and write unbiased product reviews.
